' -6 ciaimeucl.- '221461) This .invention relates to dispensing caps for containers. Y l YIt is an object of the invention'to provide a simple and economical dispensing cap, more particularlyl suitable for talcum powder and the like, v`vthat is readily moved into andK properly retained in open and shut'positions.

'With this general object in view the invention consists inthe features, combinations, details'of construction and arrangements of parts which Vwill first be described in connection with the acr`constructed in accordance with the inventionv companying ydrawing and pointed out'.v

In the drawing: I j Figure 1` is a vertical sectional view of acap then more particularly and showing the cap in open position;

Figure A2 is a similar View of thecap in closed` position; and

Figure 3 is a top plan view of` one ofthe parts'A Referring io the'dr'awing, the capcomp'rises a stationary body portion*y and a movable portion. As here shown as an example, the stationary bo'dy portion comprises a skirt 5 for fitting over Ythe top 'of-a bottle,` jar, can or the like. `It' will be understoodv thatthe skirtl may be given any` desired rformationto conform to the particular container involved. I The upper part of the body portion is in the nature of a housing 6, open at the top. The top rim is dished downwardly, as

at '7, and terminatesin an inwardly oblique ange 8 defining the opening. Between the housing 6 and the skirt 5 is an inwardly extending bead-like abutment 9 hereinafter referred to.

, Y. The movablevportion ofthecap here illustrated as an example includes a closure plate 10. In

l the closure plate in either of its positions.

the open position of the cap (Figure 1) this plate lies within the dished'po'rtion 7 of the cap housing, but is of a smaller diameter than the latter.'

. This leaves an annular passagell between the cap housing and the closure plate -for the discharge of the contents of the container. In the closed position (Figure 2) theV closure plate 10 moves into contact with flange 8 and so shuts ,oi the annular passage 11. l

There is provided means for yieldingly holding here shown as an example, secured to the closure plate, as later described, is aso-called bird-cage"l The bottom of this skirt is formed with an out-k wardly extending bead 14 which cooperates with abutment 9` in holding the' movable portion ofl the y cap in position.v I

The movable unit of the ample, there'is provided a ngergpiece or knob 11,5.

has a pin 16 passing through holes in closure plate f cap may be moved'in-f ,any ysuitable manner. Asn-here shown as an eX- 1 r l As a Aconvenient method .of assembly, this knob 10 yandthe dome 12 of the,bird-cage spring,thev

end of thepinthen being headed, as atl'l, in the'ffv l )e5 1 vWhen the cap is open, bead 14 of the spring ele-gl manner Vof a rivet.

ment engages the upper side; ofjabtment9 (Figure 1) and holds Athe Ymovable unit'inup''orAk open position. The unit' is moved down toclosed f positionl by a downward pressurethereon. This Y 70 force causes vspring Yarms ,13 ,to becompressed f'' radially; bead 14 sliding over abutment 9; A s

soon as bead 14 has passed abutment, the spring arms re-expand and the beadsnaps into position,A

below the abutment.' The engagement of closure plate 10 with iiange'8vnot only shuts voff the dis'- pensing passage but serves also as 'ajstop to limit the downward movement of the movable unit.

A The parts are Anow held closed, upward oropening movement being opposed by the'engagement yof nange 14 with, the underside ofi-abutment?) (Figure 2).

`TQ @pen the cap, the A`movable unit is pulled upwardly; YThe spring varms'a'reagainccmpressed above the shoulder 18 so that when the cap is in l open position (Figure 1) the contents can pass ange 8 and reach the annular discharge openingll. Whenthe cap is in closed position, these extensions are shut off by flange 8, thus giving an added closing effect. f y During movement ofthe movable unit the latter. is guided by having a sliding bearing in the rim of ange 8.
